Letters Patent Ne. 109.329, dated November 15, 1870.

vIMPROVEMENT IN SHUTTER-FASTENERS.

The Schedule referred to in these Lettexs Patent and making part of the lame.

the following to be a fnll, clear, and exactdescriptionl ofthe same, reference being hadto the accompanying dra win g and to the letters ot' `reference. marked thereon.

The nature ot1 my invention consists in the construcl tion cfa blind-fastener, which is composed of a spring catch, anotched lever for operating it, and a bar and latch for locking the catch so as to hold it securely in place when either open o1` shut; and

It also consists in the combination ot certain other devices with a spring, for preventing the blind from sagging back and forth when open, as will hereafter he more fully set forth and dcscribed.

Figure l is a side elevation of a blind or shutter, to which my improvement is attached Figure 2 is a similar view ot the spring ior preventiing the shutter from sagging;

Figure 3 is a side elevation ot' the spring catch for holding the shutter; and

Figure 4 is an edge view of the same.

A represents a common blind or shutter, having a small metal frame, B, attached .to its lower corner.

Within this frame is placed a spring catch, C, which is always kept pressed downward by means ot' a spring, D, so that it will hold the shutter either open or shut on the' catches E and F, and which is guided in its upward alud downward movements by a screw or holt, a.

In thc'side ot' this catch (i there is a number of cogs formed, within which the cogs of the pivoted lever G mesh, so as to raise the catch up over the stops E and F. t

Pvotcd to thc end of the lever G is a longrbar, I1', by means of which the catch G is operated.

Near the outer end of this bar thereis a slot, c, formed, through which passes the screw or bolt d, and which acts both as a guide and a support for the bar.

livotcd to the screw d is a stop, I, which swings around, as shown bythe dotted lines, so that the shoulder, formed on its end, will rest upon and against the projection 11, formed on thc face of the bar H. As soon 'as this stop is brought to bear'against the projection yu it acts as a lock, so as to prevent the bar from moving back and forth, and, through the bar,

llocks the catch C, so that it can he moved .neither up nor down.

Secured to the side ot' the house is a stop, F, which` not only serves t0 hohl the shutter hack when open, but also serves as a support to it.

Secured to this stop is aspring, L, which keeps the catch C pressed forward against the shoulder o, so as to prevent the shutter from sagging back and fortlrin the wind.

o -As thc bar H extends nearly across the shutter, the

e catch can b"e raised from the stp, when open, so as to close it, without reaching as far out as with the ones now in use.

Having thus described my invention,

W hat I claim as new, and desire to secure by Letters Patent, is

1. The combination vofthe catch C, spring D, lever t G, and slotted operating-bar H, extending toward theinner edge ot the shutter, all as and for the purpose set fort-h.

2. The slot-ted operating-bar 1I, with its projection "n, combined with the fastening-button I and guidepin (I, all arranged as set forth.

3. The combination of the rigid stoplr with beveled notch O, the spring L, and the spring catch Ce, working in the blind, all as and for the purpose set forth. Y
